Sidebar 3: Measurements
I examined the measured behavior of the YBA Design WD202 using the Audio Precision SYS2722 system (see www.ap.com and "As We See It" in the January 2008 issue), as well as, for some tests, my Audio Precision System One Dual Domain and the Miller Jitter Analyzer. I mainly drove the YBA with the SYS2722's AES/EBU output; I also used the USB 2.0 output of my Intel MacBook running OS10.4.11 for the testing, playing back WAV files using Bias Peak 6.2. Examining the WD202's USB properties with the USB Prober program for the Mac identified the device as "USB Audio DAC…
Leben Hi-Fi Stereo Company is a very small company in Amagasaki City, Japan, that hand-builds an exquisite line of vacuum-tube audio electronics. I find it intriguing that Taku Hyodo, founder and main man of Leben, once worked for the comparatively huge Luxman firm. Years back, Luxman went through various corporate owners and spent some time wandering in the desert, before returning to its high-end audio heritage. Whether, as I suspect, Leben was founded during Luxman's years of ownership by car-stereo maker Alpine, or if Hyodo simply wanted to be the captain of his own destiny, I don't know…
So one of the first things I did after receiving both the Leben amp and ProAc loudspeakers was to play that Brian Cheney CD-R. I came to the conclusion that the CdF person had perhaps been overcautious—although at the time I felt that the intervention had probably been warranted. So, what gives?
I can think of a few possibilities. The hotel room, though small, could have been much less lively than my listening room. The CS600 used at FSI was apparently set up to use EL34 tubes, while my review sample has 6L6GC tubes—but that difference is only the 4W between 28 and 32Wpc. I also think…
It starts quietly enough, with a simple falling-fifth motif, but the first movement of Sergei Rachmaninoff's neglected Piano Sonata 1 develops into a work of epic proportions nearly 40 minutes in length, with haunting melodies, massive dynamic contrasts, and lush, sensual harmonies.
Back in 1990, when Stereophile first recorded Canadian pianist Robert Silverman, the repertoire was Brahms. But during the sessions I told Robert that someday I'd like to record him performing the two Rachmaninoff sonatas. "I've already recorded the first sonata," he said. "It was released as a Marquis LP in…
In June 2007, I again recorded Minnesotan male choir Cantus live on location, this time in the glorious acoustic of Sauder Concert Hall at Goshen College, in Goshen, Indiana. The resultant CD, While You Are Alive (Cantus CTS-1208), is the eighth I have engineered of the group; it is a collection of 20th- and 21st-century works that explores, illuminates, and celebrates all stages of life, from birth to death.
While You Are Alive (Cantus CTS1208) features works by such luminaries as Eric Whitacre, Peteris Vasks, and Veljo Tormis, as well as four world-premiere recordings of works…

Michael Fremer comes walking down the long, vinyl-lined hall that leads to his cluttered listening room, a tall stack of compact discs balanced awkwardly in his arms. He looks up to find that we are there, too, waiting for him. Caught by surprise, he…
Released in July, Live at Otto's Shrunken Head (STPH020-2) is the latest Stereophile CD from reviewer Bob Reina's jazz quartet, Attention Screen. Unlike the group's first CD, Live at Merkin Hall (STPH018-2, released in 2007), which was recorded with multiple microphones, I captured the eight improvisations on Live at Otto's using a single pair of mikes.
Otto's Shrunken Head, of course, is nothing like Merkin Hall. Near Lincoln Center, Merkin is a proper concert hall with plush seating for about 450 people. It features a stage large enough for an entire orchestra, and is known…
"My vision for the future is one where all manufacturers sell their products directly to the end user. In this way, even the audiophiles in Dead Horse, Alaska can have access to all the audio manufacturing community has to offer." Thus wrote loudspeaker designer David Fokos in a letter introducing his new company Icon Acoustics to the press at Stereophile's High End Hi-Fi show in San Mateo, CA last April (footnote 1). Mr. Fokos, a Cornell graduate who for some years worked for Conrad-Johnson Design and designed that company's well-regarded Synthesis and Sonographe loudspeaker models, feels…
